Now this is a slippery suspect.

When police tried to arrest a man for openly masturbating on 69th Street Tuesday he led them on a high-speed chase through the streets of Upper Darby and when he crashed his car and tried to flee on foot, a tube of KY Jelly spilled out of his vehicle, according to police.

Upper Darby Police Superintendent Michael Chitwood said police began receiving calls around 6 p.m. Tuesday about a man exposing himself to passersby on 69th Street near Walnut. When police arrived on scene, they found Charles Dockery, 36, sitting in the passenger's seat of his car with the door open and no pants or underwear on, Chitwood said.

As police approached his car, Dockery jumped into the driver's seat and sped away, nearly hitting one officer and injuring another, Chitwood said.

He then continued through the streets and hit two occupied cars and a third parked car, police said. After hitting the parked car, Dockery jumped out of his vehicle and as he did so, a tube of KY Jelly fell out of his car, according to Chitwood.

Following a brief foot chase, Dockery was arrested and charged with open lewdness, aggravated assault on police and related offenses.

"I'm sure the KY jelly is being held for evidence," Chitwood said. "I don't think we did a forensic exam on his penis."
